Copies src to dest. If src is a directory, this method copies all its contents recursively. If dest is a directory, copies src to dest/src.
src can be a list of files.
If dereference_root is true, this method dereference tree root.
If remove_destination is true, this method removes each destination file before copy.
Example
# Installing Ruby library "mylib" under the site_ruby FileUtils.rm_r site_ruby + '/mylib', force: true FileUtils.cp_r 'lib/', site_ruby + '/mylib' # Examples of copying several files to target directory. FileUtils.cp_r %w(mail.rb field.rb debug/), site_ruby + '/tmail' FileUtils.cp_r Dir.glob('*.rb'), '/home/foo/lib/ruby', noop: true, verbose: true # If you want to copy all contents of a directory instead of the # directory itself, c.f. src/x -> dest/x, src/y -> dest/y, # use following code. FileUtils.cp_r 'src/.', 'dest' # cp_r('src', 'dest') makes dest/src, # but this doesn't.
